Tool for grouting groove on pile side of steel pipe pile

Abstract

The invention discloses a tool for a grouting groove on the pile side of a steel pipe pile, and belongs to the technical field of bridge construction, the tool at least comprises three groups of pressure-bearing mechanisms, the multiple groups of pressure-bearing mechanisms are connected end to end through bolts, each pressure-bearing mechanism comprises a bottom plate seat, and a plurality of special-shaped rib plates are arranged at one end of each bottom plate seat; one end of the pressure bearing mechanism is provided with special-shaped rib plates, the other end of the pressure bearing mechanism is provided with connecting plates corresponding to the special-shaped rib plates in number, mounting grooves are formed in the two sides of the top ends of the special-shaped rib plates, hydraulic buffering mechanisms are embedded in the mounting grooves, and roller frames are arranged below the pressure bearing mechanism. According to the invention, the pipe body of the steel pipe pile can be effectively protected from being damaged, the service life of the pressure-bearing mechanism is prolonged, and the limiting space formed between the adjacent special-shaped rib plates can avoid the grouting groove on the pile side of the steel pipe pile, so that the welded grouting groove is protected from being damaged, and the smooth rotation of the steel pipe pile is ensured; and second meshing teeth matched with the first meshing teeth of the rollers are arranged at the lower end of the bottom plate seat, so that the stability of the device can be improved, and slipping of the rollers and the pressure-bearing mechanism is avoided.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a tool for a grouting groove on the side of a steel pipe pile. Background technique [0002] At present, with the development of bridge science and technology and the application of large-scale machinery and equipment in bridge construction, large-diameter steel pipe piles are more widely used in bridge foundations. Under the conditions of poor geological conditions, in order to meet the bearing capacity requirements of bridges, steel pipe piles can use pile side grouting to improve the bearing capacity of pile foundations. Grouting grooves, grouting the pile side of each grouting groove to improve the bearing capacity of the steel pipe piles. [0003] In order to ensure that the grouting grooves on the side of the steel pipe piles can be welded evenly along the entire circumference of the piles, it is required that the steel pipe piles can be rotated alo...

AI Technical Summary

Problems solved by technology

In the related technology, due to the welding of the grout groove on the side of the steel pipe pile, it is necessary to rotate the steel pipe pile and weld the grout groove at the top of the steel pipe pile, and the large-diameter steel pipe pile roller frame will interfere with the grout groove , unable to meet the rotation requirements of steel pipe piles with grouting grooves on the pile side; when using a crane to hoist large steel pipe piles to the roller frame, there is no buffer mechanism, which is easy to bump and damage the steel pipe pile body and roller equipment
